The Study
Insulinotropic effect of different formula of very low calorie protein supplemented diets in obesity.
This study just watched what happened to five women’s blood after they ate four different diets for a few days. It didn’t test if the diets caused the changes — it just saw what happened. So we can’t say the diets made the changes, only that they happened together.
